This professional-grade PE High-Carbon Steel Nail Cable Clip Set offers a permanent and efficient solution for indoor wire and cable routing. The clips are integrally molded from high-grade PE material and sharp, reinforced high-carbon steel nails. The PE clip body provides excellent elasticity, aging resistance, and impact strength, while the thickened steel nails are designed to resist bending, breaking, or cap loss during secure installation into concrete, brick, or wooden structures. The set includes 300 pieces total, with 100-pieces each of three sizes (approx. 0.24 in. 0.35 in. 0.47 in. inner diameter) to perfectly accommodate various round cables such as TV coaxial, Ethernet, and household AC wires. The coil-hugging design ensures a firm lock to prevent loosening from vibration or pulling, making it an ideal choice for achieving neat, safe, and code-compliant electrical installations.
